Well, I'm glad we have someone here who knows a lot about aircraft. Have you flown these big jets? I just think the First Officer would know about all of these tracking systems, IMHO. Anyway, unless there's a way to turn off that AHM transponder, it doesn't bode well for the aircraft and passengers.

If they could turn it off, an ideal time for a hijacker to do so would be after the first 2 pings and right before the last ping to make everybody think it's crashed. Some of these terrorists are pretty crafty.

Since MAL did not subscribe to AHM data and since non of the 777 experts I have heard on TV know about the AHM system why do you think any of the MAL pilots knew about it?
